Looking at the dates on the books in the Gerber guide, it doesn't appear that Weird Comics was on the stands any earlier than any other Fox books. However, what I might speculate is that as Weird was a new title at that time that Fox may have had the cover already drawn up by Fine in order to ensure that the second issue made it to the stands. Given Fox's legendary cheapness that may be a bit much to speculate, but I'm quite certain that Weird 2 is Lou Fine. (as another comparison, look at Mystery Men 9 with the alien skeleton's showing through their skin, a la the woman on Weird 2)
